UNITED STATES FFICE-e PATENT HENRY P. OSTRUM, OF NEW HAVEN, CONNECTICUT.

BOX -NAILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 269,316, dated December 19, 1882,

Application filed July 26, 1882. (No model.)

To all whom it may concern:

Be it known that I, HENRY I. OSTRUM, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have invented certain new and usefulImprovementsinBox-NailingMachines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in box-nailing machines;

and it consists in thecoustruction and arrangement of parts for feeding and driving the nails,

as will be hereinafter more fully set forth.

In the annexed drawings, Figure l is a plan view of my improved machine. Fig. 2 is a front elevation. Fig. 3 is a side elevation.

Fig. 4 is a detail view, showing the manner of feeding the nails to the driver. Fig. 5 is a plan view of the driver. Fig. 6 is a side view of the same, and Fig. 7 is a detail view.

A represents the frame of the machine, having a bed or table, B. At the rear of this bed is an upright frame, A, for sustaining the hoppers and nail-feeding troughs, as will be hereinafter explained. A treadle, a, is pivoted at a to the frame A a short distance above the floor. A ball or weight, b, is secured to the treadle at its rear end for the purpose of bringing the treadleback to its normal position when released.

Pivoted to the treadle, near the weight b, is a connecting-rod, c, the other end of which is pivoted to a short arm or crank, d, rigidly secured to a rock-shaft, C. This shaft C extends f on the stationary bed E.

g represents a stop or abutment bar, which rests onthe side bars,f, and extends across the tablef. By means of a set-screw, 9, engaging with holes formed in the side bars, the bar 9 can be adjusted on said bars ff to suit the varying sizes of boxes to be nailed.

Secured to the sliding table f are uprights or standards D D, which are connected by a bar or piece, D, that is secured by a set-screw, d, in the upright D. This bar D acts as a stop or guide for the box. Lugs E, on the backs of the standards D D, form bearings for a rod. 2', to which are adjustably attached the slotted metal points L, forming the lower ends of the nail-conductors. To a lug, h, on the standard D, is pivoted a connecting-rod, G, the other end of which is pivoted to the side of the frame H. A shaft, .j, is journaled in bearings j on the stationary table or bed 13, to which shaft are secured the nail-drivers lc-k.

Across the top of the lrame A extends a series of hoppers, J, into which the nails are placed. To the mouths of these hoppers are bolted a series of inclined troughs, I, having narrow slits or slots 2" in their tops, into and down which the nails slide. A guard or capplate, 1, extends transversely across the tops of the troughs I, and serves the purpose of setting up the nails in the slits, so that they will. slide down one at'teranother, with their heads resting on top of said slits i, and with their shanks in the troughs I, as shown in Fig. 4. The ends of the slits 'i are enlarged or terminate in square holes of suficient size to permit the heads of the nails to drop into a receptacle or notch, l, in a plate, I, (see Fig. 7,) when the sliding plate It is retracted or drawn back (see Fig. 4) by means of the wed g'e-shaped projections H on the ends of the pivoted frame H, being elevated or raised out of the grooves k The plates 7." and l are guided in their motion by means of set-screws and slots Z. (See Fig. 1.) These sliding plates are returned to their normal positions by means of the spiral springs in, and springs h may be employed to limit their movements. hen the projections H enter the grooves k they push back the plate l and permit the nails to drop into short spouts I, forming the upper parts of the conductors. Connected to these spouts are flexible tubes K, through which the nails pass to the slotted points I1. An opening or slot,

n. in the under side of each point L, permits the nails to drop lengthwise into a grooved plate, M, which is securedto the sliding table f. In the grooves of this plate M the ends of the points L lie, and by shifting these points from one groove to another the spaces between the nails can be varied as desired. Owing to the adjustable connection of the points with the shaft 6 this is readily accomplished.

The nail-drivers 7c are each provided on the under side with a punch, 0, adapted to drive the nails when the tablef is pushed back under the drivers, thus forcing the nails into the box. The drivers It have sufficient play on the shaft j to facilitate their action.

It will be observed that the points L will pass or be lifted back into the recesses 19 when the table f is under the drivers It, thus keeping them out of the way and permitting the nails to enter the box.

In many box-nailing machines the nails are placed in the feeding device by boys. Should that be done in this machine the hoppers and inclined guides would be dispensed with.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. In a box-nailing machine,thecombination of the sliding plate Z, tube K, slotted points L, and drivers 7;, substantially as shown and described.

2. Inabox-nailing machine, the combination of the hoppers J, slotted troughs I, sliding plates ls l, spouts I, tubes K, slotted points L, and drivers It, substantially as shown and described.

3. In a box-nailing machine, the combination of the drivers, 70, mounted on a rod, 7', supported in suitable bearings, the sliding table f, provided with means, substantially as described, for holding a box, mechanism for conducting the nails to a grooved plate on the sliding table, and means, substantially as described, for operating said table, substantially as set forth.

4.. In a box-nailing machine, the combination of the sliding table f, having a grooved plate,

M, and provided with devices for holding a box, the hoppers J, slotted troughs I, sliding plates 70 l, spouts I, tubes K, slotted points L, drivers It, and suitable operating mechanism, substantially as described.

. 5. In a box-nailing machine, the combination of the hoppers J, slotted troughs I, cap orcrossplate I, sliding plates k l, pivoted frame H, having pointed projections H, the spouts I, tubes K, slotted points L, drivers k, sliding tablef, and suitable connecting, supporting, and operating mechanism, substantially as described.

6. In a box-nailing machine, thecombination of the drivers It, slidingtablef,having grooved plate M, and standards D D, provided with lugs E E, the slotted points L L, mounted on a rod, '5, supported in said lugs, and means for connecting the points with suitable feed devices, substantiully as described. a

7. In a box-nailing machine, the combination of the drivers It, the sliding table f, having grooved plate M, standards D D, and adjustable stop g, and feeding and operating mechanism, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY P. OSTRUM.
